A few months ago, I helped my elderly father to complete his 2013 IRA Minimum Required Distribution from his four (4) IRAs. We did this by closing one of the smaller IRA accounts. That account balance was just slightly greater than the calculations (from the sum of the end of year balances from all 4 IRA accounts) showed that he needed to withdraw for 2013.

I have just discovered that one of the three (3) remaining IRAs is actually not an IRA at all. It is a 403b. Does the 403b have separate Minimum Required Distribution requirements that I must still meet? Or does our overall withdrawal for 2013 cover both his IRAs and this 403b?
